This invention relates to a turbulence manifold for interpositionbetween one or more carburetors and the intake manifold ofan internalcombustion engine.

The invention aims to provide, in a manner as hereinafter set forth, amanifold of the class referred to for not only throughly mixing fuel andair, but also for expanding the same after it passes from a carburetoror carburetors and before it enters the intake manifold `of the engine,`and whereby when supplied to lthe combustion chamber of the engine itresults in the engine operating with more power, at less expense, and atthe same time overcomes the knock or ping of the motor on the hardestpull or on. a hill and under such conditions reducing gear shifting.

The invention further aimsto provide, in a manner as hereinafter setforth, a turbulence manifold including a pair of superposed bodilyrevolving groups of vanes, fins or turbulence plates for thoroughlymixing air and -fuel on the travel thereof towards thecombustion'chamber of an internal combustion engine and with `theaforesaid groups .bodily revolyingfrom the suction of the engine. l

`The invention further aims to provide, in a manner as hereinafter setforth, a turbulence l manifold for the .purpose referred to which issimple in its construction and arrangement, read- 'ily installedrelative to a carburetor and an inconsists of the novel construction andarrange-- ment of parts as will be more specically.de scribed andillustrated inthe accompanying drawing, wherein is shown an embodimentof the invention, but it is to be understood that changes, variationsandmodifications may be resorted to which fall within the scope of the in-`vention as claimed.

In the drawing: y Figure 1 is a longitudinal sectional vView of aturbulence manifold in accordance with this in-` vention showing theadaptation thereof vwith respect to a pair of carburetors and the intake7 manifold of an internal combustion engine,

Figure 2 is a section on line 2--2 Figure 1, and

Figure 3 is a fragmentary View in front ele' vation illustrating theform of blank from which the fins, vanes and turbulence plates areformed.

With reference tothe drawing, the turbulence manifold, in accordancewithv this invention, is

generally indicated at I and it is shown by way of example in connectionwith a pair of carburetors 2, 3 and thev intake manifold 4 of aninternal combustion engine. The carburetors -2, 3 as shown are providedwith valve controlled fuel conducting pipes 5, 6 respectively, which arecommon to and open into alreceiver 'I having an outlet 8. By way ofexample the carburetor 2 may be for gasoline and the carburetorl 3 foroil. It is to be understood that the manifold I may be used solely inconnection with a single carburetor and'if so, its fuel conducting pipewill be connected directly to the intake to be referred to of themanifold I.

The manifold I consists of a pair of superimposed oppositely disposedsections 9, I0 of rounded form each provided with a pair of oppositelydisposed anges Il, I2 extending lengthwise' thereof. The flanges II, I 2of the section 9 are seated uponthe flanges II, I2 of the section IIJ.The flanges of one section are detachably secured to the flanges of theother section by the holdfast means I3.

The section 9 includes a bodypart I4 of shelllike form open at itsbottom and having formed integral therewith a side wall I5 formed withan opening I6 and an outward directed annular sleeve I1. The section 9also includes a side `wall I8 vformed with an opening I9 and anoutwardly directed integral annularsleeve 29. Integral with the innervface of the side wall I5 and extending to a point in close proximity tothe side wall I8 is a tubular member 2| con- @nected to the body part I4by a coupling piece 22. The side wall I8 is secured with the bodyportion AI4 by welding or otherwise. The tubular member 2| `provides achamber 26 for a rotatable turbulence element V2l to be hereinafterreferred to. The tubular member 2I is formed with a fuel intake 28 and apair of fueloutlets 29 for the chamber 25.

The section I0 includes a body part or portion 30 of shell-like formwhich is open at its top and has formed integral therewith a side wall3l `provided with an opening 32 and an outwardly directed annular sleeve33. The section I0 also includes a side wall `34| formed with an opening35 and an outwardly directed integral annular sleeve 36. Integralwiththe inner face of the side wall 3| and extending to a point in closeproximity to the side Wall 34 is ar tu-L bular member 35a, which isconnected to the body part 30 by a coupling piece 36a. 'I'he side Wall3|. is secured to the body portion 30 by welding or otherwise. Thetubular member 35a provides a chamber 39 for a rotatable turbulenceelement 4|) to be hereinafter referred to. The tubular'member 35a isformed with a pair of fuel intakes 3| and a fuel outlet 42.

Integral with the body portion I4 and with the top of the tubular member2|, as well as opening into the latter is a fuel conductor 43 whichcommunicates with and is connected to the outlet 8, as at 44. Formedintegral with the body portion 30 and With the bottom of the tubularmember 35a, as` well as opening into the latter is a fuel outlet pipe44, which is connected to the intake manifold 4, as at 45.

The bottom of the tubular member 2| abuts the top of the tubular member35a and the outlets 29 of the tubular member 2|` register with theintakes 4| of the'tubular member 35a. The chamber 26 constitutes anupper mixing chamber and the chamber 39 a lower mixing chamber.

The sections 9, IE) are arranged in superimposed abutting relation, andthe end walls I5, 3| and the couplers 22, 35a co act,with said bodyportions or parts to form a heating chamber 46, which surrounds themixing chambers 26 and 39. The chamber 46 includes an intake 41, whichis adapted to communicate with the exhaust manifold of the engine. Thechamber 46 has an outlet 48. The utilizing of the chamber 46 is for thepurpose of having the heat contained therein expand the fuel in themixing chambers 2S and 39 during the travel of the fuel therethrough`The elements 21, 40 are of like form and each consists of a shaft 49 andfour rows of torsionally twisted fins, vanes or turbulence plates, whichwill `be hereinafter referred to as vanes. Each row is formed from astrip 50 of metallic material of the desired thickness transverselyslitted, as at 5|, and the material fre-ed by the slits is torsionallytwisted to form the vanes 52. The slits terminate adjacent the inner endof the strip to form an anchoring part 53, which is secured to the shaft49. The strips are of less length than the length of the shaft and areso disposed relative to Vthe'latter whereby the shaft will project fromeach end of the strip. The projecting ends of the shaft of theturbulence element 21 extend into the sleeves |1, 2|) and are surroundedby roller bearings 54. The shaft 49 of the turbulence element 40 extendsinto the sleeves 33, 36 and are surrounded by roller bearings 55. Theelements 21 and 4|) Aare bodily revolved from the suction action of theengine. Arranged against the outer face of the walls l5 and 3| andenclosing the sleeves |1, 23 is a housin-g 51 providing an oil well51'#1 for the purpose of lubricating one end of the shafts 4B of theelements 21, 40. The housing 51 is suitably secured to the sections 9,I0.

Positioned against and suitably secured to the side walls I9 and 34 is ahousing 6| which encloses the sleeves 20 and 36 and provides an oil well62 for the shafts of the elements 21, 40.

The fuel supplied from a carburetor or a pair of carburetors enters thechamber 26 and is mixed by the element 21, as the latter is bodilyrevolved from the suction of the engine. The fuel after being acted uponin the chamber 26 by the element 21 passes into the chamber 39 where itis acted upon by the bodily revolving element 4|), which is operatedfrom the suction ofthe engine and it passes from chamber 39 into theintake manifold 4 and from there into the combustion chamber of theengine. The action is such that the fuel and the air are thoroughlymixed and are also expanded due to the heat contained in the chamber 46.The fuel and air are so thoroughly mixed before they enter thecombustion chamber of the engine whereby when they are supplied to suchchamber the result is that the engine will operate with more power, atless expense, and at the same time the use of the fuel will overcome theknock or ping on the hardest pull or on a hill, and under suchconditions reducing gear shifting.
